You offer a great service for downloadable media. I am in need of a shopping cart system to sell my mp3 files. I am planning to sell an album online. However, I have a unique requirement. I want the buyer to be able to input the final price for the item. There should be a preconfigured minimum of $2 and no maximum price. Therefore, one buyer may decide to pay $3 while another may decide to pay $300, and yet another will decide to pay $2.01. Is it possible to set up this type of shopping cart with E-Junkie?
